Achromatic Lens

Achromatic Lenses consist of two or more elements, usually of crown and
flint glass that have been corrected for chromatic aberration with respect to
two selected wavelengths.

Red Optronics provides achromatic lenses consisting of two elements. These
lenses have considerably reduced not only chromatic aberration bust also
spherical aberration and coma aberration. These are designed with respect
to three wavelength 480nm, 546.1nm and 643.8nm. They are best used in
replacing singlet where improved performance is required.
